In the app.layout below, I am trying to incorporate related, interactive elements like text area and a datatable inside the AccordionItem tags. But I keep receiving this error message:
)
^
SyntaxError: positional argument follows keyword argument
I tried to bold the line in the code pasted below causing the error message, but that does not work. Specifically, it is line numbers 25-26 which I capitalized and separated from the rest of the code with a line space. If I remove the “),” causing the error message, it returns but in reference to the “]” at line number 38-39.
Can someone please explain what is wrong and how to resolve the issue?
The information I find online talks about this error message as it pertains to Python functions, not Dash app layouts. And I am trying to insert a text area into an Accordion item. Perhaps I am not looking in the right place, but I am also not finding the question answered on this forum.
Thank you very much for reviewing my question.
external_stylesheets=[dbc.themes.SUPERHERO]
app = dash.Dash(external_stylesheets=external_stylesheets)
app.layout = html.Div(
[ html.Br(),
html.H5("Welcome to the Ingredible's Nutrition Assistant"),
html.Br(),
dbc.Accordion(
[
dbc.AccordionItem(
"This is the content of the first section",
title="Step 1",
item_id="acc_textarea",
html.Br(), html.Br(),
html.Label("Please paste your recipe here."),
dcc.Textarea(id='recipe-textarea',
value='',
style={'width': '80%', 'height':500},
placeholder='Please note: All information in brackets or parantheses will be deleted.'),
html.Br(), html.Br(),
html.Button('Submit Recipe', id='recipe-textarea-submit-button', n_clicks=0),
html.Br(), html.Br(),
HTML.DIV(ID="MSG"),
This is the line that seems to be causing the problem:
),
dbc.AccordionItem(
"This is the content of the second section",
title="Item 2",
item_id="acc_datatable",
),
dbc.AccordionItem(
"This is the content of the third section",
title="Item 3",
item_id="acc_report",
),
],
id="accordion",
active_item="acc_textarea",
),
html.Div(id="accordion-contents", className="mt-3"),
]
)
@app.callback(
Output("accordion-contents", "children"),
[Input("accordion", "active_item")],
)
def change_item(item):
return f"Item selected: {item}"
